Article from February 2020 and the last thing in the article states...
I call BS, Onstar and GM don't care, they know insurance will pay and the owner may end up buying a new GM truck, so just one more sale for them! I have started taking the fuel pump relay out of the truck at night hoping that causes them enough issues, if they do try to get mine, that they bail on the theft. I think I will take a look at all the fuses and relays to see how many I can remove to disable it, I doubt they'll have a pocket full of the right things to repopulate and drive it away
